Description

Technical Field

[0001] The utility model relates to the technical field of four-column hydraulic presses, in particular to a four-column hydraulic press for blasting products. Background Art

[0026] The locking mechanism 03 includes a guide rod 31, a sliding block 32, a push rod 33, a first spring 34, a locking hole 35, a locking pin 36 and a connecting rod 37.

[0028] Example 2

[0029] like Figures 1 to 4As shown, it includes a hydraulic mechanism 01, and also includes two sets of fixing mechanisms 02, a locking mechanism 03, a safety mechanism 04, an emergency mechanism 05 and an adjustment mechanism 06. The fixing mechanism 02 is installed on the hydraulic mechanism 01, the locking mechanism 03 is installed on the fixing mechanism 02, the safety mechanism 04 is installed on the hydraulic mechanism 01, the emergency mechanism 05 is installed on the hydraulic mechanism 01, and the adjustment mechanism 06 is installed in the emergency mechanism 05;

[0030] The hydraulic mechanism 01 facilitates hydraulic pressure on the explosive product, the locking mechanism 03 assists the fixing mechanism 02 to install and fix the hydraulic mechanism 01, the insurance mechanism 04 prevents the operator's arm from being injured when it is in the hydraulic mechanism 01, and the adjustment mechanism 06 drives the emergency mechanism 05 to perform emergency insurance when the hydraulic mechanism 01 is repaired;

[0031] The safety mechanism 04 includes four sliding rods 41, four pressure sensors 42, four extrusion plates 43, four limit plates 44 and four second springs 45. The four sliding rods 41 are slidably mounted on the mounting plate at the bottom end of the hydraulic cylinder 13, the four pressure sensors 42 are mounted on the mounting plate, the four extrusion plates 43 are respectively mounted on the bottom ends of the four sliding rods 41, the four limit plates 44 are respectively mounted on the top ends of the four sliding rods 41, and the four second springs 45 are respectively connected to each group of limit plates 44 and the pressure sensors 42;

[0032] The emergency mechanism 05 includes a sliding cylinder 51 and a support plate 53. The sliding cylinder 51 is mounted on the top of the mounting plate. A sliding groove 52 is provided on the sliding cylinder 51. The sliding cylinder 51 is slidably mounted on the mounting frame 12. The support plate 53 is slidably mounted in the sliding groove 52.

[0033] The adjustment mechanism 06 includes a lead screw 61 and a handle 62. The lead screw 61 is rotatably mounted in the sliding cylinder 51. The support plate 53 is threadedly matched with the lead screw 61. The handle 62 is mounted on the lead screw 61.

[0034] The hydraulic mechanism 01 is used to facilitate hydraulic pressure on the explosive product, and the locking mechanism 03 assists the fixing mechanism 02 to install and fix the hydraulic mechanism 01. When the hydraulic mechanism 01 is working normally, the mounting plate is driven down by opening the hydraulic cylinder 13, and then the extrusion plate 43 is driven down, and the extrusion plate 43 contacts the fixing box 21, so that the sliding rod 41 slides on the mounting plate, and then the pressure sensor 42 is pulled by the second spring 45. At this time, the tension values ​​of the four pressure sensors 42 are consistent, and it is judged to be safe. When the operator's arm is located at the bottom end of the hydraulic cylinder 13, the extrusion plate 43 contacts the arm and squeezes the sliding rod 41 to slide on the mounting plate. At this time, the tension values ​​of the four pressure sensors 42 are different, which is abnormal, so the pressure sensor 42 controls the limit plate 44 to stop working to protect the safety of the operator. When the hydraulic mechanism 01 needs to be repaired, the handle 62 is turned to drive the screw 61 to rotate, and then the support plate 53 is driven to slide in the sliding groove 52 through the threaded relationship, and then the support plate 53 and the mounting frame 12 are blocked to perform emergency protection on the whole.

[0035] like Figures 1 to 5 As shown, the utility model is a four-column hydraulic press for blasting products. When it is working, when the blasting product is to be hydraulically pressed, the upper mold 15 is driven to descend by opening the hydraulic cylinder 13, and then the blasting product is pressed by the lower mold 14 and the upper mold 15. When the lower mold 14 and the upper mold 15 are to be installed, the push rod 33 is first pulled to make the first spring 34 contract, and at the same time, the sliding block 32 slides on the guide rod 31, and then the sliding plates of the lower mold 14 and the upper mold 15 are slidably installed in the slideway surrounded by the two fixed grooves 22. When the locking pin 36 is aligned with the locking hole 35, the push rod 33 is released, and the sliding block 32 is pushed to slide on the guide rod 31 by the elasticity of the first spring 34, and then the locking pin 36 is pushed into the locking hole 35 by the connecting rod 37 to fix the lower mold 14 and the upper mold 15. When the hydraulic mechanism 01 is working normally, the hydraulic cylinder 13 is opened to drive the upper mold 15 to descend, and then the lower mold 14 and the upper mold 15 are pressed by the lower mold 14 and the upper mold 15. The movable mounting plate descends, thereby causing the extrusion plate 43 to descend, and the extrusion plate 43 contacts the fixed box 21, so that the sliding rod 41 slides on the mounting plate, and then the pressure sensor 42 is pulled by the second spring 45. At this time, the tension values ​​of the four pressure sensors 42 are consistent, and it is judged to be safe. When the operator's arm is at the bottom end of the hydraulic cylinder 13, the extrusion plate 43 contacts the arm and squeezes the sliding rod 41 to slide on the mounting plate. At this time, the tension values ​​of the four pressure sensors 42 are different, which is abnormal. Therefore, the pressure sensor 42 controls the limit plate 44 to stop working to protect the operator's safety. When the hydraulic mechanism 01 needs to be repaired, the handle 62 is turned to drive the screw 61 to rotate, and then the support plate 53 is driven to slide in the sliding groove 52 through the threaded relationship, and then the support plate 53 and the mounting frame 12 are blocked to provide emergency protection for the whole.

[0036] The hydraulic cylinder 13 and the pressure sensor 42 of the utility model are purchased on the market, and the technicians in the industry only need to install and operate them according to the accompanying instruction manuals, without the need for the technicians in the field to make creative efforts.

[0037] The main function achieved by the utility model is that during the working process of the four-column hydraulic press, the mold can be easily replaced, thereby improving convenience and safety.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
